Go to Carrier Operations → Data Management → Carriers.
Carrier Operators can delete carriers that have not been submitted to the Carrier Administrator for activation.
Locate the Carrier in the Carriers list by using the available filters or by navigating through the pages at the bottom of the list. The status of the carrier will be Onboarding/Prospect.
Click on the icon at the end of the carrier row and select the Delete option.
The carrier will be deleted immediately and will no longer be available from the Carriers list.
